RAND recalculates whenever a worksheet is opened or changed.Note: In Excel 365, the RANDARRAY function is another way to generate multiple random numbers, and to generate random numbers between two values. The RANDBETWEEN function can generate random integers between to numbers: =RANDBETWEEN(1,9) // random number between 1-9 To generate a random number between a and b, you can use a formula like this: RAND()*(b-a)+aįor example, to generate a random number between 1 and 9: RAND()*(9-1)+1 To generate a set of random numbers in multiple cells, select the cells, enter =RAND() and press control + enter. To get a single random number that doesn't change when the worksheet is calculated, enter =RAND() in the formulas bar and then press F9 to convert the formula into its result. To stop random numbers from being updated, copy the cells that contain RAND to the clipboard, then use Paste Special > Values to convert to a static result. The RAND function will calculate a new result each time a worksheet is edited. RAND takes no arguments: =RAND() // returns number like 0.073979356 We guarantee a connection within 30 seconds and a customized solution within 20 minutes.RAND is a volatile function, and can cause performance issues in large or complex worksheets.

Most of the time, the problem you will need to solve will be more complex than a simple application of a formula or function. Therefore, the result of the formula in the cell E3 is “Jacob”. In this example, this function returned 3, so the INDEX returns the value from the third row. 2 Answers Sorted by: 3 Use the following function, remember Bernoulli is a special case of binomial distribution with 1 trial binom.inv (1, p, rand ()) will generate 1 or 0 with chance of 1 being p. The row_num is the result of the RANDBETWEEN function, which returns a random number between 1 and 8. The INDEX function searches the B3:B10 range. Using the INDEX function to get a random name from the list To apply the formula, we need to follow these steps: The row_num is RANDBETWEEN(1, ROWS(B3:B10)), while the column_num is 1. In the cell E3, we want to get the random name from the list of names in the range B3:B10. Data that we will use in the example Get a Random Name from the List of Names The result will be stored in the cell E3įigure 2. In column B (“Names”), we have the list of names for which we want to find the random name. array – an array for which we want to get the total number of rows.top – a value to which we want to get a random value.bottom – a value from which we want to get a random value.The parameters of the RANDBETWEEN function are: It’s a non-mandatory parameter and if it’s omitted it’s by default 1. – a column from which we want to get a value.row_num – a row from which we want to get a value.array – a list of values where we want to find a value from a certain position.The parameters of the INDEX function are: The final result of the functions Syntax of the INDEX formula This step by step tutorial will assist all levels of Excel users in understanding how to get a random value from the list using these 3 functions.įigure 1. Excel allows us to get a random value from a list or table, by using the INDEX, RANDBETWEEN and ROWS functions.
